SOME PHYSICAL PROPERTIES OF CZO THIN FILMS PRODUCED BY A NOVEL MAGNETIC SPIN COATING TECHNIQUE

Abstract

Semiconductor ZnO thin films, whose physical properties can be modified by doping various metals are used in many current technological areas, from antimicrobial structures to photodedectors, to photovoltaic attacks, to sensors with various uses. The crystal structures of the ZnO thin films can be modified by changing their properties such as band gaps and optical permeability by doping with Cd, and fine films can be produced in different properties suitable for the field of use. In this study, CZO (Cd-doped ZnO) thin films were produced using a novel magnetic spin coating technique, which was developed as an alternative to production techniques carried by complex and expensive device technology. The Cd doping process was increased by 1%, 3% and 5%, and by increasing the doping to 5%, the peaks of the hexagonal CdZn structure were observed in addition to the peaks of the ZnO series. When the surface properties of the produced films were examined, it was seen that the coating was distributed homogeneously on the surface, the particle size values increased as the amount of Cd doping increased and the voids disappeared on the surface, and thus formed of nanoparticles which were held better to each other. When the optical properties of Cd doped ZnO thin films were examined, it was seen that the band gap values decreased with increasing amount of doping.
